His significance as a philosopher and teacher, and his few remaining philosophical works, have not received the same attention as his scientific and poetic writings. Al-Zamakhshari referred to him as the philosopher of the world. He taught the philosophy of Avicenna for decades in Nishapur, where Khayyám was born and buried. His mausoleum there remains a masterpiece of Iranian architecture visited by many people every year.Al-Zamakhshari AvicennaIranian architecture

Outside Iran and Persian-speaking countries, Khayyám has had an impact on literature and societies through the translation of his works and popularization by other scholars. The greatest such impact was in English-speaking countries; the English scholarThomas Hyde (1636–1703) was the first non-Persian to study him. The most influential of all was Edward FitzGerald (1809–83), [5] who made Khayyám the most famous poet of the East in the West through his celebrated translation and adaptations of Khayyám's rather small number of quatrains (Persian: رباعیات rubā ʿ iyāt) in the Rubaiyat of Omar Khayyam.Thomas HydeEdward FitzGerald [5]adaptationsquatrainsPersianRubaiyat of Omar Khayyam
